[0016] In order to make the technical methods, creative features, achieved purposes, and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0017] Example, such as Figure 4 , 5 , 7 and Figure 8As shown in the figure, in view of the problems in the prior art, the present invention provides a carbide spiral vertical milling cutter head with an extendable handle that can be disassembled, including a milling cutter head body 1. A set of rotating components 3 are fixedly installed inside the milling cutter head body 1. The inside of the rotating component 3 includes a motor 310, a small gear 311, a rotating column 312, a large gear 313, an installation box 314, and a milling cutter 315. The motor 310 is fixedly installed inside the installation frame 111. The small gear 311 is rotatably connected to the upper end of the milling cutter head body 1. The upper end of the rotating column 312 is fixedly connected to the center position inside the small gear 311, and the rotating column 312 is rotatably connected inside the milling cutter head body 1. The upper end of the large gear 313 is fixedly connected to the output shaft of the motor 310. Multiple sets of small gears 311 are meshed and connected to the large gear 313. The large gear 313 is rotatably connected to the center position of the upper end of the milling cutter head body 1. A set of rotating columns 312 are fixedly connected inside. There are gaps between the upper and lower ends of the installation box 314 and the side walls of the U-shaped groove 110. The milling cutter 315 is slidably connected inside the installation box 314.

[0018] After the motor 310 in the present invention is started, it will drive the large gear 313 to rotate. Since multiple sets of small gears 311 are meshed and connected to the large gear 313, when the large gear 313 rotates, it will also drive the small gears 311 to rotate together. The small gears 311 will drive the rotating column 312 to rotate. And the rotating column 312 is fixedly connected to the inside of the installation box 314. So when the rotating column 312 rotates, the installation box 314 and the milling cutter 315 will also rotate accordingly, thereby changing the installation angle of the milling cutter 315. By adjusting the angle of the milling cutter 315, it can adapt to different processing materials and processing requirements, enabling the milling cutter head to handle a wider range of processing tasks, and can optimize the cutting force distribution during the cutting process, reduce the cutting resistance, and improve the cutting efficiency. When the milling cutter 315 is adjusted to a suitable angle, it can also reduce the vibration caused by unbalanced cutting force and improve the anti-vibration performance of the machine tool.

[0019] As Figure 2 、 3 and Figure 6 shown, a set of anti-vibration components 5 are fixedly installed on the side wall of the installation box 314. The inside of the anti-vibration component 5 includes a rubber plate 510, a spring 511, and a rubber block 512. One side of the rubber plate 510 is fixedly connected to the side wall of the installation box 314. The other side of the rubber plate 510 is fixedly connected to one end of the spring 511. The other end of the spring 511 is fixedly connected to one side of the rubber block 512. The other side of the rubber block 512 is fixedly connected to the inner wall of the U-shaped groove 110.

[0020] During the rotation of the mounting box 314 in the present invention, the spring 511 mounted on the side will be compressed. At this time, the spring 511 is compressed by the force, which can absorb most of the energy driven by the vibration. Moreover, a set of rubber plates 510 are installed between the spring 511 and the mounting box 314, which can also absorb part of the energy. At this time, the vibration impact on the mounting box 314 will be greatly reduced, thereby preventing the milling cutter 315 from being severely worn due to vibration, and effectively improving the service life of the milling cutter 315.

[0021] As Figure 5 , 6 and Figure 8 shown, a set of telescopic components 4 are installed on one side of the mounting box 314. The inside of the telescopic component 4 includes a fixed plate 410, a telescopic rod 411, a connecting frame 412 and a chute 413. The fixed plate 410 is fixedly installed on the rear side wall of the mounting box 314. Two groups of telescopic rods 411 are fixedly connected to the side wall of the fixed plate 410. There is a gap between the telescopic rod 411 and the side wall of the mounting box 314. The output end of the telescopic rod 411 is fixedly connected to one side of the connecting frame 412. The convex block installed on the connecting frame 412 is fixedly connected to the side wall of the milling cutter 315, and the convex block installed on the connecting frame 412 is slidably connected inside the chute 413. The chute 413 is opened on the side wall of the mounting box 314. A set of air blowing components 2 are fixedly installed inside the milling cutter disc body 1. The inside of the air blowing component 2 includes a blower 210, an air duct 211 and an air outlet box 212. Multiple groups of blowers 210 are fixedly installed inside the mounting frame 111. A set of air ducts 211 are fixedly installed on the upper end of the blower 210. The air outlet at the lower end of the blower 210 is fixedly connected to one end of a hose, and the other end of the hose is fixedly connected to the upper end of the air outlet box 212. The air outlet box 212 is fixedly installed inside the U-shaped groove 110. Multiple air outlet holes are opened on one side of the air outlet box 212. Multiple U-shaped grooves 110 are opened inside the milling cutter disc body 1. Each group of U-shaped grooves 110 corresponds to a set of rotating components 3. The upper end of the milling cutter disc body 1 is fixedly connected to a mounting frame 111. The mounting frame 111 is fixedly connected to the air duct 211. The upper end of the mounting frame 111 is fixedly connected to a connecting disc 112. A threaded connection port is opened inside the connecting disc 112.

[0022] In the present invention, when the cutting position needs to be changed to be located inside the workpiece, and the milling cutter 315 is not long enough to extend to this position, the two sets of telescopic rods 411 can be operated to start at the same time, which will push the connecting frame 412 to slide forward inside the slide groove 413, thereby driving the milling cutter 315 to slide inside the installation box 314, and the extended length of the milling cutter 315 can be adjusted according to needs. While cutting, the blower 210 will also be started, which will suck external air into the interior, and then transport it to the interior of the air outlet box 212 through a set of hoses, and finally blow it out through the holes opened on the air outlet box 212, thereby blowing out the debris attached to the inside of the U-shaped groove 110 to prevent subsequent cleaning difficulties, and the gas blown out can also effectively cool the milling cutter 315 to prevent its temperature from being too high.

[0023] Working principle: when it is necessary to adjust the installation angle of the milling cutter 315 to adapt to different materials and processing requirements, the operating motor 310 is started, which will drive the large gear 313 to rotate, and a plurality of groups of small gears 311 are meshed and connected to the large gear 313, so when the large gear 313 rotates, it will also drive the small gears 311 to rotate together, and the small gears 311 will drive the rotating column 312 to rotate, and the rotating column 312 is fixedly connected to the inside of the installation box 314, so when the rotating column 312 rotates, the installation box 314 and the milling cutter 315 will also rotate accordingly, thereby changing the installation angle of the milling cutter 315, and the installation box 314 will begin to squeeze the spring 511 installed on the side while rotating. At this time, the spring 511 is compressed and can absorb most of the energy brought by the vibration, and a group of rubber plates 510 are also installed between the spring 511 and the installation box 314, which can also absorb part of the energy brought. 4 will be greatly reduced, thereby preventing the milling cutter 315 from being aggravated by the vibration, effectively increasing the service life of the milling cutter 315. When the cutting position needs to be changed to be located inside the workpiece, and the milling cutter 315 is not long enough to extend to this position, the two sets of telescopic rods 411 can be operated to start at the same time, which will push the connecting frame 412 to slide forward inside the slide slot 413, thereby driving the milling cutter 315 to slide inside the installation box 314, and the extended length of the milling cutter 315 can be adjusted according to needs. At the same time as cutting, the blower 210 will also be started, which will suck external air into the interior, and then transport it to the interior of the air outlet box 212 through a set of hoses, and finally blow it out through the holes opened on the air outlet box 212, thereby blowing out the debris attached to the inside of the U-shaped groove 110, preventing subsequent cleaning difficulties, and the blown gas can also effectively cool the milling cutter 315 to prevent its temperature from being too high and aggravating wear.
